Understanding Others' Roles Based on Perspective Taking in Coordinated Group Behavior
Interacting through understanding others' roles based on perspective taking is important for achieving a group goal. However, complex and dynamic interactions, such as group non-verbal behaviors with three or more members, have not been fully examined. Our theoretical contribution expands the range of the theory applied to problem solving and learning in cognitive science to group non-verbal behavior with three members. In this study, participant triads repeatedly engaged in a coordinated drawing task, operating reels to adjust the thread tensions and moving a pen connected to the three threads to draw an equilateral triangle. We measured the pen positions and tensions. Analyzing group behavior quantitatively, the results showed that the role of stretching the thread a little significantly contributed to improved performance for drawing quickly. It suggests that maintaining overall balance through individuals' understanding others' roles based on perspective taking, is key to coordination.
